引領(lǐng)化學(xué)吸附技術(shù)前沿-美國麥克儀器公司AutoChem II 2920

美國麥克儀器 2011-11-22 | 閱讀：4571

自美國麥克儀器公司AutoChem系列研究級高性能全自動程序升溫化學(xué)吸附儀問世以來，憑借其過硬的技術(shù)優(yōu)勢引領(lǐng)化學(xué)吸附技術(shù)發(fā)展方向，解決用戶化學(xué)吸附測試中的難題，并逐漸成為化學(xué)吸附分析的領(lǐng)導(dǎo)者。麥克儀器公司始終追隨客戶的需求，不斷升級改進(jìn)自己的技術(shù)， AutoChem 系列儀器已經(jīng)經(jīng)過了幾代的升級演變。自AutoChem II 2920發(fā)布至今，它已經(jīng)成為全球各個著名大學(xué)以及研究結(jié)構(gòu)的首選儀器。其中不乏中國知名學(xué)府和研究院，華東理工、華南理工、天津大學(xué)、復(fù)旦大學(xué)、廈門大學(xué)、北京科技大學(xué)、北京工業(yè)大學(xué)、北京化工研究院、中石化石油化工科學(xué)研究院、中科院大連化物所、中海油天津化工研究院、蘭州石油化工研究院、上海石油化工研究院等等都是AutoChem II2920的用戶。

AutoChem II 2920具有如下技術(shù)特征：

4個內(nèi)部溫度控制區(qū)可獨(dú)立加熱，最高達(dá)250 ℃（TCD）。這樣可以防止氣體在流動過程中凝結(jié)與吸附。
小體積的內(nèi)部管路保證了高分辨率與快速探測器響應(yīng)，并在計算氣體體積時減少錯誤。
高度敏感的線性熱傳導(dǎo)檢測器（TCD ）確保校準(zhǔn)體積在整個峰范圍內(nèi)保持恒定，從而峰面積與反應(yīng)氣體體積成正比關(guān)系
四個高精度的質(zhì)量流量控制器提供非常準(zhǔn)確、可程序控制的氣體流量控制，保證了穩(wěn)定的基線和氣體體積的準(zhǔn)確測定。
鍍金TCD具有超強(qiáng)抗氨腐蝕性和抗氧化性，從而盡可能降低檢測器損耗。
開合式加熱爐能加熱石英樣品反應(yīng)器到1100℃ 。可設(shè)定任意數(shù)量的升溫速率和內(nèi)置方法，方便定制的實(shí)驗(yàn)。 KwikCool功能冷卻爐可使?fàn)t內(nèi)溫度迅速下降到環(huán)境溫度，減少分析時間，提高測試量。
分別用于制備、載氣和LOOP氣的十二路進(jìn)氣口允許連接更多的氣體，進(jìn)行更為復(fù)雜的實(shí)驗(yàn)。例如TPR / TPO循環(huán)。
質(zhì)譜儀端口和集成軟件允許同時在熱導(dǎo)檢測器和質(zhì)譜儀上進(jìn)行檢測。
蒸汽發(fā)生器允許蒸汽吸附反應(yīng)，例如吡啶、苯和水。
CryoCooler冷浴槽可以在-110℃低溫條件下開始進(jìn)行反應(yīng)，滿足貴金屬催化反應(yīng)研究。
同時AutoChem II 2920也可以根據(jù)客戶實(shí)際需要進(jìn)行各種定制。
